    One of the main features of the electrocardiogram (ECG) is the R-R interval. However, R-R interval based analysis does not detect distortions on the other ECG waves, such as P-wave distortions for atrial fibrillation (AF). In this context, this work proposes to analyze the voltage variation in each heartbeat using statistical moments. The heartbeats were obtained from the MIT-BIH Arrhythmia, MIT-BIH AF and MIT-BIH Normal Sinus Rhythm. The results obtained in this work can be used to support decision-making in clinical practice with a 99.78% and 100% accuracy for arrhythmia and AF diagnoses, respectively.

    A 78-year-old female without systemic medical history was admitted to the hospital after a falling accident. She experienced lower back pain and progressive weakness of bilateral lower limbs. A diagnosis of compression fractures of T12 and L2 was made.

    Iatrogenic aortic injuries are a rare complication of spinal surgery. While there is no consensus on the best treatment for these patients, there have been successful reports of both open and endovascular techniques. We report a case of delayed thoracic iatrogenic aortic injury following spinal surgery that was treated with TEVAR and screw removal. A pedicle screw that was placed during treatment of a compression fracture was found, three years later, to be piercing the thoracic aorta. A 28mm x 28 mm x 100mm thoracic stent graft was deployed in standard fashion to cover the area of injury, and the screw was removed. The operation was successful and patient was followed for one year with no complications relating to her repair. TEVAR prior to the screw removal provides appropriate coverage of the injury and appears to be a safe and durable option.

    Persistence of a left superior vena cava (PLSVC) has been reported in 0.3%0.4% of candidates for pacemaker; another rare anomaly (incidence 8 / 100,000) is dextrocardia. We report the case of a 67-year old man, without any cardiological history, with prolonged episodes of bradycardia, secondary to a second degree type 1 and 2 block, and AV 2:1 block phases, which was placed the indication for a bicameral PM implantation. At the chest radiograph the radiologist suggested the presence of dextrocardia. During the pacemaker implantation procedure through the left subclavian venous access, the guide wire proceeded on an abnormal way, remaining in the left side of the chest. The angiography showed PLSVC. In this case, the complexity to the intervention was represented by dextroposition of the heart.

    Diabetes mellitus (DM)is an established risk factor for the development and progression of macrovascular disease, and is associated with worse outcomes inthe context of myocardial infarction and congestive heart failure.Despite the availability of a broad spectrum of pharmacotherapies for the management of DM, these do not appear to significantly abrogate conferred risk of morbidity and mortality. This review provides a succinct overview of the primary findings from two recent clinical trials EMPA-REG and LEADER and explores potential mechanisms that may underpin the observed benefits.
